OIL SEPARATOR AND PURIFIER.

Application filed November 5, 1913.

To all whom, it may concern:

Be it known that I, GEORGE C. RENSINK, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented anew and useful Oil Separator and Purifier, of which the following is a specification.

This invention relates to improvements in oil separators and purifiers.

The object of the invention is to provide a device of this character, comprising a main tank in which the water of condensation from a stationary engine or the engine of a steam-propelled vehicle is given a circuitous course from its entrance therein to its exit therefrom, whereby a complete separation of the Oil from the water is effected; and a supplemental tank in which the water is freed from all sediment and foreign substances.

Further, to provide a main tank in which the water is given a circuitous course from its entrance to its exit, and Which is arranged to receive sediment at various noncommunicating points in the course of travel of said water, faucets being provided for drawing ofi' said sediment, said tank being also arranged to prevent it from becoming either air-bound or Steam-bound during the passage of the water through the tank, a supplemental tank being provided to receive the water from the main tank and to thoroughly filter the same, said tanks being provided with float valves, which permit the escape of air or steam when the water in said tanks is below a predetermined level.

These objects are accomplished by the device illustrated in the accompanying drawings, in which:

Figure 1 is a vertical, sectional view through the two tanks comprising my improved oil separator and purifier. Fig. 2 is a side view of a portion of the main tank, partly broken away to show a float valve located at the upper end of said tank. Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2. Fig. 4 is a horizontal, sectional view on the line 4-4 of Fig. 1. Fig. 5 is a vertical, sectional view through the cap of the main tank at right angles to the section illustrated in Fig. 1; and Fig. 6 is a similar sectional view to that shown in Fig. 5, but looking in the diametrically opposite direction.

Referring to the accompanying drawings:

The numeral 1 indicates the main tank in which the separation of the oil from the water takes place. This tank is closed by a concavo-convex cap or cover 2, which is tightly secured thereon in any suitable manner, and this cap is preferably cast iron on account of the nature of its construction. An inlet passage 3 extends from the marginal edge of the cap toward its axial center and terminates in an axial semi-spherical chamber 4, having a relatively large threaded opening 5 extending through its bottom, the walls of the inlet, the chamber 4 and thecap being integrally connected. An outlet passage 6 extends through the cap at a diametrically opposite point from the inlet passage 3, and through the adjacent side of the chamber 4, and terminates in the chamber in an elbow 7, the lower end of which is internally threaded, and extends into, and is concentric with the opening 5 in the said chamber 4, but is of considerably less diameter than the said opening. The elbow and outlet are also integral with the cap and with the wall of the chamber 4, but there is no communication between the inlet and outlet passages, as Will be understood by reference to Figs. 1 and 3. A pipe 8 is screwed into the elbow 7 and extends down to within a short distance of the bottom of the tank. A short pipe or jacket 9 surrounds the upper portion of the pipe 8, and screws into the opening 5 of the chamber 4. The lower end of the pipe 9 is closed, save for an opening which is formed therein, through which the pipe 8 passes, the pipe fitting the said opening tightly. A plurality of radially disposed tubes 10, are screwed into the jacket 9, adjacent to its lower end, and the outer ends of these tubes are upturned and extend adjacent to the sides of the tank. A diaphram 11, extends across the tank, below the tubes 10. This diaphram comprises a slightly conical bottom having a relatively large central opening 12. The outer margin of the bottom terminates in an annular wall 13, which is concentric with the wall of the tank, but spaced therefrom so as to form an annular space 14, between the said wall 13 and the wall of the tank. The wall 13 terminates in a horizontal annular step 15, and the step terminates in a flange 16, which is secured to the Wall of the tank.

Slightly below the diaphragm 11, and

parallel with it, is a second diaphragm 17,

part of the present invention.

having a central hub, which tightly surrounds the pipe 8. The circumferential edge of this diaphragm is secured to a cylindrical wall or partition 18, which is spaced from the wall of the tank and extends from a point near the bottom of the tank to within a short distance of the step portion 15, of the diaphragm 11, a space being left between it and'the annular wall 13 of the said diaphragm. A jacket 19 surrounds the lower portion of the pipe 8. This jacket rests upon and is secured to the bottom of the tank and extends up to within a short distance of the diaphragm 17, its upper end being provided with a flaring flange 20, which is parallel with the said diaphragm 17. A drain faucet 21 is positioned at the oil level in the tank; a drain pipe 22, leads from the bottom of the diaphragm 17, through the Wall of the tank, and is pro vided with a faucet 23; a drain pipe 24 leads from the bottom of the jacket 19, through the wall of the tank, and is provided with a faucet 25, and a faucet 26 is positioned at the bottom of the tank.

The tank above described is the one in which the separation of the oil from the water takes place. The water, carrying the oil, enters the inlet 3, through a pipe 27, which leads from a cooler 28, of any preferred type, said cooler forming no part of the present invention. The cooler is connected by a pipe29, with a suitable receiving tank, which is supplied from a condenser which receives the steam from the engine, the water being forced into the main separating tank by a pump connected with the receiving tank. The receiving tank, the pump and the condenser and engine are omitted from the drawings, as they form no A cylindrical Wall or baflle plate 30, is secured to the cap 2, and extends down a suitable distance into the tank. This bafiie plate is provided with a multiplicity of perforations 31, and it is adapted to prevent undue agitation or splashing of the water in the tank, particularly where the separator is used in connection with steam propelled vehicles. A float valve 32, is supported in a suitable cage 33, attached to the cap 2, and this valve normally closes an outlet 34,

which permits the escape of either steam or air, when the water in the tank drops below the level of the bottom of the cage 33, as will be fully explained hereinafter. The step 15, of the diaphragm 11, is provided with a circular series of small apertures 35,

and the wall 18 is also provided with simi lar apertures 36, the object of which will 7 appear later.

A pipe 37, connects the outlet 6, of the main tank 1, with the lower end of a tank 38, in which the water is purified by being freed of all sediment and foreign substances bottom 42, the apex of which is in line with and slightly above the nozzle 39. The receptacle 40, extends up to within a suitable distance of the top of the tank 38, and between its upper end and the wall of the tankis supported a circular horizontal screen 43, of suitable mesh. A funnel-shaped pipe 44, extends down a suitable distance into the receptacle 40, and over its lower flared end is secured a screen 45. The upper end of this funnel-shaped pipe is connected with an outlet pipe 46, which extends out through the wall of the tank, and leads to a receiving tank-not shownwhich is connected with the boiler. A drain pipe 47, extends from the bottom of the receptacle 40,'through the wall of the tank, and is provided with a faucet 48, and a faucet 49 is positioned in the wall of the tank adjacent to the bottom thereof. A float valve 50 is supported in a cage 51, secured to the cap 52, of the tank, and this valve normally closes an outlet 53,

*in the said cap, but permits the escape of.

either air or steam when the water in the tank falls below, or fails to reach a'predetermined level.

In Fig. 2, a gage 54 is shown on the upper portion of the tank 1, by means of which the water and oil level in the tank may be ascertained.

In operation, water of condensation is pumped into the tank 1., through the inlet 3, and passes into the chamber 4 and down into the jacket 9, whence it passes out and upward, through the tubes 10, and falls upon the diaphragm 11, whence it flows into the diaphragm 17. As the water above the diaphragm 17 increases in volume, it is forced out between the diaphragms 11 and 17, and over the upper edge of the wall 18, the sediment meantime precipitating to the bottom of the diaphragm 17 whence it may be drawn oil through the faucet 23. As the water overflows the upper edgeof the wall 18, it passes down between the said wall 18 and the wall of the tank and into the tank. It then rises in the chamber inclosed by the wall 18, and the air or steam between the upper surface of the water and the diaphragm 17, escapes through the apertures 36 and 35, thereb relieving the pressure upon the water. deposited in the bottom of the tank, and is drawn off, when necessary, through the faucet 26. When the water rises to the level of the flange 20, it overflows into the jacket 19, and sediment collected in the bottom of said jacket may be drawn off through the ediment in the water is i integers faucet 25. From. the-jacht 19, thewater passes up through the pipe 8, to the outlet 6, whence it passes threugh; the pipe 37, to the purifying tank-38.. Should there' be 1a. volwater passes freely through the tank. h].

the purifying tank, the water from the pipe 37, passes out through the nozzle 39 against the conical bottom of'the receptacle 1&0, by which it is 'divided'tora separated, and passes up around the-sides of the receptacle 4:0, and through thescreen 43,- into the receptacle-4 0, whence it passesthrough the'screenlo, on the lower end -of vthe funnel-like pipe l-l, through said pipezand out through the outlet pip 46. The sediment separated by the screen 43, being-of greaterc specific gravity than the water, falls by .gravity and settles to the bottom of thetank, thus preventing the screen from becoming clogged, and is drawn ofl by the fancet 49,while that-separated by-the screen =settles to the bottom of the receptacle40, leaving the screen free, as in the cas of the screen 43, and is drawn off by the faucet 48. en the water is discharged'from thepipe 445, itis purified to such an extent that it-is in condition to be returned to theboiler.
